Mechanical characterization of the mucoadhesive film: folding endurance, elongation and tensile strength of the 10 mg Montelukast (MTK) film exposed to normal (T0) and freezing conditions (T 15 days and 30 days). Results are shown as the average of three to eighth films (mean with SD).
| Time | T0 | 15 Days | 30 Days |
|---|---|---|---|
| Folding endurance | >10 | >10 | >10 |
| Elongation at break (%) | 62 ± 6 | 69 ± 7 | 65 ± 9 |
| Tensile strength (kPa) | 128 ± 10 | 115 ± 15 | 123 ± 13 |
